What is the over 2.5 mile long submersible causeway which connects Noirmoutier island to the French mainland?
Passage du Gois is a submersible causeway in the Bay of Bourgneuf, linking the island of Noirmoutier to the mainland in the department of Vendée, in France. Twice a day, for an hour or two, the tide goes out and the causeway becomes visible and accessible to traffic. For the rest of the day, it remains flooded under 1.3 to 4 meters of water and cannot be used.
Although causeways such as Passage du Gois exist in other places (there is one in the county of Jindo in Korea), the uniqueness of Passage du Gois lies in its exceptional length of over 4 km or 2.5 miles.

How the heck did they build this causeway with only an hour or two available each day?

Lindsey Fussell, very carefully, don't you imagine! 😂😂😂 No, that was a good question! That was probably what most of us asked ourselves when we read and saw the photo! 😊👍

I've got to learn more about this. A simple rain storm will create chuckholes in our roads! Thank you.

There's one that links Lindisfarne island to Mainland England (Northumberland). Not quite as long but significant as it's to a popular tourist destination National Trust and English Heritage properties.

Why didn't they build it higher where the tide covers it up?
